To-ctZZ 107mm t may concern.-

Be it known that we, SEEArro ARTEAGA and ELTsEo DEL VALLE, bothresidents of the city, county, and State of New York, have invented newand useful. Improvements in a Gombined Goal-Cart and Weighing-Scale; andwe do hereby declare that the following is a full and exact descriptionthereof, reference being had to the accompanying drawings, and to theletters of reference marked thereon, making apart 0i this speciiication,in which- Figure l is an elevation in perspective of our improved coalweighing and registering cart; Fig. 2, a transverse section takenlongitudinally through its axle; Fig. 3, a detached rear elevation ofthe mechanism for operating the indicating and registering dials, andFig. 4 a similar View illustrating a change in the positions thereof.

Our invention relates to that class of carts -or vehicles in which thebody is supported upon springs combined with a weighing ap paratus toindicate the weight of the load placed thereon.

It has for its object to provide in a simple and economical form atwowheeled cart for the delivery of coal,wliich shall be constructedwith a weighing apparatus so arranged as that it will not only indicatethe weight of coal loaded into the cart, but when the load is deliveredwill register the same upon suitable dials, so that the number ofdeliveries made in a day and the total weight thereof will be registeredfor reference.

In the accompanying` drawings, A represents the body of a twowheeledcoal-cart of any suitable torni, and preferably of such dimensions asthat it will contain one ton of coal.

B is the upper cross board or bar, B the lower cross-bar, and G C theside bars, of a suspension-frame, within which the body A is supportedupon. a series of spiral springs, D D, preferably four in number, andeach adapted to carry one-fourth oi" a ton weight. ,These springs areinterposed between the lower bar, B', and a central bolster-bar, A',under the bottom of the body. The suspension-frame B B C C is mountedupon the wheels E E of the cart by means of spindles i" E', secured tothe lateral bars of the frame, to project therefrom in a right line witheach other, at a distance above the lower bar, B, equal to the height ofthe springs, as shown in Fig. 2; or the spindles may form the ends of acranked axle bent at each end topass under the bar B and support thesame. The springs D D and the lower bar, B', are inclosed between twoparallel side plates or boards, A, made fast to the under side of thebody, to project there from, forming virtually a box whose bottom andends are formed by the bar B and side bars, CC, and whose sides and topare formed by the projecting plates and the portion of the bottom of thecartbody included between them.

F F are the side bars, pivoted each at one end to one of theaXialspindles E E', and which are made to extend thence to the front of thebody, where they are connected together by a cross-piece, K, to whichthe shafts T T are secured. The body is thus left free to play up anddown between the side bars, the line, of draft of the shafts upon theaxes of theA wheels being constant and direct, irrespective of theposition of the body. The axial spindlcs E E serve as pivots upon whichthe body of the cart may turn for dumping, and the front end of the cartis secured, to prevent it from tipping, by means oi' the cross-piece Kand a loose bar, "G, which is led in the customary manner at each endthrough a staple, b, proj ecting' from the cross-piece K, (see Fig. 1,)through blocks secured to the body, or similar equivalent devicesforming no part or' this invention. A fixed bar, H, is secured acrossthe top of the body to extend from one side thereof to the other underthe upper board or bar, B, oi the axial frame.

A vertical dial-plate, YV, is iixed upon the upper bar or board, B, ofthe frame, mounted on the axle, and a spindle, L, is fitted to rotate insuitable bearings at the center thereof. rlhe inner end ofthe spindle Lterminates in a crank-arm, M, whose outer end is connected by a rod, N,to the crossbar H, attached to the body, and the cranl; is so adj ustedas that, as the eartbody A drops away from the upper bar, B, by reasonof the load placed thereon, the crank-arm M will be turned from itsupper to its lowcrniost position, over an arc somewhat less than ahalt-circle, to avoid a deadpoint at either end of its stroke. Asemi-rotation of the spindle L will thus be produced,

`and this movement of the spindle will be indicated upon the t'ace ofthedial \V by means of an index-hand, l, fixed on the end of' the spindleto sweep over a scale marked upon the dial-face, and which is marked toindicate one ton at a full stroke ol" the hand, and is subdivided toindicate, bythe proportional movements of the hand, proportionaldivisions of the ton, so that when a haltton is loaded into the cart thehand will sweep over one-half of the scale and point to the tigures ofthe scale indicating a haltton.

To provide for the registration of theainount delivered from thecart--as, for example, to register each ton or haltton so delivered-tworatchet-wheels, R and R', of different diameters are pivoted upon therear ot' the dial-plate XV, one on either side of the crank-rod N. Thespindles which carry the ratchet-wheels R R pass through the dial-plateand carry, respectively, pointers e c upon their opposite ends.Spring-pawls it and u', tixed to the dial-plate \V, engage,respectively, the teeth of the ratchet-wheels lt it', to prevent areverse movement thereof, and are made so to bear nponthe periphery ofeach wheel as to prevent it from moving easily. The smaller wheel, R, isso located with reference to this bar N and its line of movement asthat, when the bar is depressed one-halt` its stroke, and therebyswnngover to one side ofthe center, it will cause a doubleheaded pawl, S,pivot'ed to one side oi' the rod N and automatically maintained bysprings t t in a position central to this side ot' the rod, to engage atooth of the smaller ratchetwheel, lil, so that when the rod N moves upto its tirstposition it will cause said wheel to rotate a distanceproportionate to the length of said movement. The number of teeth uponthe ratchet It is such as that each haltstroke upward of the rod N willbring a tooth into position to be engaged by the pawl on the rod when itnext drops half its stroke. The dial V, over which the pointer e,carried by the spindle ot' the ratchet R, moves, is so graduated as thateach movement ofthe ratchet will carry the pointer from one divisionthereofto the next, so that its position will indicate the number ofhalf-strokes the rod has made since the pointer was last set to zero.XVhen, however, the rod N drops its full stroke, by reason ot' theloading ofthe cart with a ltull ton ot' coal, the pawl S on the rod willbe carried down past the smaller ratchetwheel, R, (the springs tt,governing the pawl, allowing it to yield sufliciently to pass readilybythe projecting ratchet-tooth thereon,) and as the rod swings towardthe central line the pawl will be carried toward and past the proximatetoot-h of the larger ratchet-wheel, It, the tooth being heldinpositionby the spring-pawl u, which engages the wheel, so that when the rod Nmoves upward it will canse the wheel to turn. llhc engagement of thepawl S with this larger wheel, lt, will operate to swing the pawl clearoftheproximate tooth in the smaller wheel, R, until it has passed clearof the latter, as shown in Fig. 4.

The pointer e, carried by thelarger ratchetwheel, R', serves to indicatein the same inanner as that ofthe smaller wheel the number of lullstrokes made by the rod since thepointer was last placed at zero.

The cart is made moreeompletc by pivoting to its rear end a swingingchute, Y. This chute Y is pivotcd to the edge of the bottom piece of thebox ol' the cart, so as to swing up and cover and close an opening, Z,at its .rear end. X'Vhen the load is to be dumped into a coal-hole, thechute Y is swung out to thehole, so that the coal falling out throughthe opening Z in the rear end of the cart will pass down the chute tothe hole. A second section, Y', may be hinged to the first section, Y,ol" the chute by detachable hooks c c, so as to extend it il" need be.ln throwing ont the chute the weight thereof tends to facilitate thetipping of the cart backward.

ln the use of my invention the index-hand l? ot' the scale will point tozero when the cart is empty, and the hands @and c' of the ton andhalf-ton registers are set each at Zero before the delivery ol'` coal toany one party is commenced. Each time the cart is loaded thereafter theindex-hand l) will indicate when the proper weight hasbeen placedtherein. It' but a half-ton is loaded, the springs D D will be depressedbut about one half and the rod N drawn down one halt' its i'ull strokeonly, so that its pawl S will be brought in position to engage only thesmall ratchet-wheel R, actu ating the pointer e on theone-half-ton-registering dial. So soon as the cart is emptied, so as toallow the rod N to rise, its upward movement will carry the pointer e onsaid register forward one point or division of the scale. lf a full tonbe placed in the cart, the rod N being fully depressed by the droppingof the body A its pawl S will be carried down and over into engagementwith the large ratchetwheel It', actuating the pointer of the one-tonregister, and so soon as the cartis emptied will, in moving up, turnsaid ratchet-wheel R' one point and move its pointer e over one divisionofthe oue-ton-registering dia-l.

XVe are aware that carts and cars mounted upon springs interposedbetween the body and axle have heretofore been titted with pointers orindex-tingers attached to the body to move over scales attached to asupport carried directly upon the axle, and that this arrangement haslikewise been reversed, so that the scale is upon the yielding part orbody and the pointer upon a fixed portion carried by the axle. XVe donot therefore claim, broadly, the combination of the one part or indexof a scale with the axle and the other part or dial with the body of acart. Ourinvention relates to the construction and arrangement, inatwowheeled coal-cart, of a central transverse bar carried by a framemounted upon the two wheels of the vehicle, and within which the IOC IIO

cart-body is mounted, and provided with a dial iixed upon said bar, overwhich moves an index -pointer actuated, as described, by the changes inthe relative position of the body to said bar under varying loads,whereby the one single dial is brought prominently into View at acentral point in eonneotion with the cart to indicate Clearly the weightof the'load without any interference with the loading or unloading ofthe cart or its management.

7e Claim as our invention- 1. The suspension-frame O, mounted upon thecart-Wheels E Eand Within which the eartbody A is centrally mounted,springs D D, interposed between the body and the lower bar ofthe frame,the dial-plate XV upon the upper bar of the frame, the index-hand P,revolving in a half-circle over the dial, the Crank-spindle'L, Carryingsaid index-hand, and the rod N, Connecting the crank of the spindle withthe cart-body, all substantially in the manner and for the purposeherein set forth.

2. The combination,withthebody ofa weighing-cart, its Wheels, a framemounted upon the wheels, within which the-body is suspended, springsinterposed between the body and frame, a dial-plate secured to the upperbar of the frame, a cranked spindle rotating on said dialplate, and arod, N, secured to the body at one end and at 'the other to the rankarmof said spindle, of the ratchet-wheels R R', mounted on each side of therod N, pointers carried by their spindles, fixed pawls u u', controllingsaid ratehetsto preventa reverse movement thereof, a double-headed pawl,S, pivoted to the face of the rod N, to engage said ratchet-wheel, andsprings 't t, controlling said pawl, all substantially in the manner andfor the purpose set forth.

In testimony whereof we have signed our 4o SERAPIO ARTEAGA. ELISEO DELVALLE.
